Alright, well good luck. Just don't say I didn't tell you so. If you could have gotten them new and not used, tracked, ones I'm sure you would have. When people buy used and/or cheap parts they always tend to find the need to justify their purchase. My last advice is get rid of them while you can.

Of course I would've bought new if I had wanted to spend another $700. I love buying used things because they're almost always as well taken care of as everything I have on my car currently and it saves me a ton of money. I'm sure i'll have no problems with these coils but if I do I always have the KW lifetime warranty

If you buy used you don't have a warranty. Only the OG owner does. Like I said, get rid of them while you can. Even if you did the warranty protects against manufacture defects, not track abuse.

I can gaurentee KW will honor the warranty and replace them if I have an issue. Coilovers are meant to be tracked not babied imo so I doubt that would prevent them from replacing them. I'd call it track use not abuse. I don't even know how many times they were brought to the track but if KW coils can't handle normal track use, they shouldn't even be considered high quality coils.

If you are the second owner, and have an issue not related to manufacturing I very highly doubt that. Anyhow, good luck. If you don't take my advice so be it. I just know I would never ever put those on my personal car.

Yea to each their own I guess. I can provide KW with the receipt from the original purchase and I doubt they would be that strict if something went wrong. They're an extremely reputable company known for great customer service so i'm not worried at all. My theory behind buying all used parts is as long as they're not broken buying someones parts that have 8k on them is no different from having parts on my car that I bought new and driving them past 8k. I love saving money wherever I can so I try to buy used whenever I find a good deal and save some $$. I should have a thread up with pics and thoughts after they get installed this weekend

Yes. That black cover. I believe it's supposed to stay connected to the lower portion to keep dirt away from the piston.

Yea I checked with KW and it's not a big deal. They're like $10 so I ordered some new ones but i'm installing it anyway. They said theres no issue running without it for a while you just shouldn't do it for that long

I would suggest that anyone changing out springs or struts to inspect the dust cover before you tear into it. Its a shame if you have to reinstall a torn boot just cause you don't have one.

Strut bellow part number: 31331094749 (not sure about LCI)

Also do some research about front bump stops when buying lowering springs. Bilstein have internal bump stops, koni and stock struts need external bump stops. Koni does not supply them with their yellows. Some have been fine but I had to cut mine at the time of my eibach and koni install. I later tore it apart again to install shorter bump stops, I chose the e36 M3 (same as z3 m) as others have recommended. I wish I would have done some more research before and spared another 3 hours to tear the front suspension apart again.

So I read thru the first page and then jump to this last page. I was wondering if someone can summarize an upgrade path which would be best if you just wanted to do a full upgrade of the 2008 335xi e90 factory sport suspension?

Things I've heard that we could do (But, I'm looking for what is the best path to get it all done at once and save on labor rates). I'm looking for a daily driver car and I hate how hard the ride is currently. I'm still running the square setup stock 17" rim and RFT tires, but I'm looking to switch out to 19" staggered.

Once all this is upgraded, would my alignment shop still try to align for the e90 sport setting on the machine or would they want to align for a different setting like the M3? I've also heard that the M3 tends to get a vibration at around 80 MPH which I would probably inherit?

Any suggestions on 19" wheel size/offsets that can be run in staggered to make the wheels flush (I'm thinking about running Michelin PSS in non-winter months and go back to style 162's in the winter with All season tires for snow).

Hi guys.. I am new to the XI world. I just purchased a 06' 325xiT for my daily. Currently from the research I have gathered it looks like the best/most popular setup would be KW-V1 coils or Eibach Sport Springs w/Koni Sport Shocks? Im not sure if there is any other "cheaper" (ie. ST Coils, BC Coils, etc...) on the market yet?

I was also wanting to verify if there are any differences between the E90/92 suspension compared to the E91?
